Best carbon I have ever usedBy Marcuson 10/24/2011

This stuff really works!! Water is kept crystal clear. You don't have to use very much either, about half the volume of bituminous carbon.

Great for reactor useBy Juanon 10/14/2011

Works wonderful in the reactor.

Great very low dustBy Ryan on 10/12/2011

Very low dust, only issue I have is it floats for a little while but it's very easy to use

I noticed a difference within hours of putting it in the tank. I can use 3 cups for about a month on my 240. Would highly recommend this to everyone.

I've got a 240 gallon tank and 3 cups will last me easily a month. I notice a huge difference in water clarity after an hour of replacing with new carbon.

Used in a BRS reactor this product makes the water crystal clear!

smaller but more efficientBy Nathanon 10/4/2011

This carbon is much smaller pellets than most carbon on the market I have seen. I can imagine that is a good thing with the added surface area. Make sure you have a filter bag / sponge that will trap this stuff thou.

Works well, but very fine granules.By Kevinon 9/27/2011

The ROX carbon works well enough in my reef tank when used in a media reactor. If your tank is already in decent shape (ie. no major problem with discoloration/cloudiness, or heavy bio-load) I would recommend just getting the Lignite carbon. I could not see the value in this carbon over any other quality carbon. (If I'm going to pay double for a product, I expect it to work twice as well. Another problem with the ROX is how fine it is. As stated above, it can only be used in a media reactor. (I do recommend the BRS reactor! :) I have a freshwater cichlid tank that uses power filters. The ROX carbon can not be used in any of the flow through cartridges in my filters. It washes through the filter and dumps into my tank.

To wrap up. If you have a dirty tank that has a media reactor. I recommend the ROX. With a fairly clean tank or to just maintain already clear water, save your money and go with the lignite.

Water is really clear. Excellent carbon for the price. I will stick with this kind.

Goes a long waysBy Scotton 9/16/2011

This carbon goes a long ways. Takes very little time to rinse compared to other carbons I have used in the past, just a matter of a few seconds.
